“My immunity is weak, and the flu caught it” – such statements are not uncommon, especially in wet, cold weather. Indeed, a decrease in the body’s defenses is one of the risk factors for influenza and other acute respiratory viral infections. But not only them. Many diseases, including serious ones, can be avoided if the body is able to fight them. Indeed, immunity protects us not only from viruses, bacteria, fungi, but also from everything genetically alien, toxins produced during the life of the body, foreign cells, and genetically modified own cells. Destroys the immune system and cancer cells. That is why increasing immunity is the key to health and longevity. But first, a few words about what the immune system is and how it works.
What is immunity
The immune system includes organs and tissues in which immune cells are formed and act, which recognize and destroy foreign substances – agents. The immune system includes red bone marrow, thymus, lymph nodes, and the gastrointestinal tract. Representatives of the immune system are found in all internal organs, on the mucous membranes and skin.
Immunity can be cellular and humoral. Cellular immunity is represented by lymphocytes (a type of white blood cells) and macrophages. Lymphocytes kill harmful microorganisms (killers and helpers), suppress harmful reactions (suppressors), and macrophages swallow foreign agents.
Humoral immunity includes immunoglobulins, interferons and polysaccharides.
The immune system has a memory: it remembers those foreign substances that have entered the body, and when they meet them again, it recognizes them. This is called immunity to infections. If you had chickenpox or rubella in your childhood, your immune system will remember these infections. When they again enter the body, they will be immediately identified and destroyed. The functions of such memory are possessed by immunoglobulins, or antibodies. And although they do not live long – several weeks, they are able to transmit information to other newly formed antibodies.
We are constantly in contact with harmful microorganisms, exposed to adverse environmental influences, but remain healthy due to the accumulated immune memory. And infants receive it from the mother, in utero and through breast milk – this helps them cope with infections, while their own immune memory has not yet formed.Why is it necessary to increase immunity
The fact is that adverse environmental conditions, exposure to harmful and toxic substances, harmful food weaken the immune system. Some drugs, in particular antibiotics, also act on the immune system. Of course, in some cases, antibiotics are necessary – they help to cope with severe infections and can literally save lives. But, killing pathogens, they destroy the beneficial intestinal microflora, which plays an important role in the immune system. As a result, within 2-3 weeks after taking antibiotics, immunity is reduced, and a person can become ill again.
Weaken the immune system and foci of chronic infection. Struggling with them, the immune system may simply not cope with external influences, and as a result, a person begins to get sick. Giardia, chlamydia, herpes, caries, dysbiosis, staphylococci and streptococci – all this can lead to frequent diseases
Weak immunity in children is often caused by worms. In most cases, the child becomes infected in the summer. Kids dig in the ground, can eat poorly washed berries and fruits, swallow water when bathing, as a result – infection with parasites, weakened immunity, and after 2-3 months the child becomes ill. Therefore, in the fall, doctors recommend that all preschool children conduct an anthelmintic course, it is especially necessary for children who are often ill. Another focus of chronic infection in children is adenoids.
Who needs an increase in immunity
How to determine if you have strong immunity or not without performing expensive research? It is believed that an adult with good immunity suffers from infections (viral or intestinal) in a mild form no more than 2-3 times a year. For children after a year, the norm is slightly higher: no more than 4–5 colds in the cold season and no more than 2–3 cases of intestinal infections in the summer season. If so, then immunity is all right.
If a person is sick more often, he needs to check his immune status by donating blood for analysis. The immune status is recommended to determine those who suffer from allergies, frequent purulent diseases.
How to increase immunity
Here, a lot depends on ourselves.
First of all, it is necessary to cure all chronic infections. To do this, you may have to first conduct a study on hidden infections in order to identify all the foci.
The second point is a balanced diet. This means that the body must receive all the elements with food: proteins, fats and carbohydrates. Various diets, including the rejection of protein foods, a carbohydrate-free diet, a sharp restriction of fats in food.
